Land use is a dynamic and natural process, yet it can be controlled. Examining the trends of land use dynamics is one of the most essential pieces of information needed for natural resource management. In this study, to prepare land use change maps in the Barandozchay watershed, images from the TM, ETM+ sensors of the Landsat satellite and Sentinel-2 for the years 1990, 1995, 2000, 2005, 2010, 2016, 2020, and 2024 were used over a 34-year period. Subsequently, to predict land use for the year 2032, the CA-Markov model in the TerrSet software was utilized. Finally, for the trend of land use changes, the change intensity index and the degree of dynamics index were used to monitor land use changes. The results showed that the classified maps were produced with high accuracy and a Kappa coefficient of more than 0.80, indicating high reliability of the analyses. The analysis of land use changes showed that the most significant changes occurred in residential land use, especially in the periods 1995-2000 and 1995-2024, with growth rates of 22.66% and 267.35%, respectively. This growth indicates rapid development of residential and urban areas, likely due to population growth and housing demand in this region. Additionally, in the period 2020-2024, the expansion of irrigated lands and orchards with a growth rate of 0.42% was observed, which could be due to increased demand for agricultural products and improved agricultural techniques. The prediction for 2032 indicates that the area of residential regions will increase to 95.19 square kilometers and irrigated lands and orchards to 584.64 square kilometers, while rainfed lands and rangelands will decrease. The analysis of the integrated dynamic degree index (Ktotal) also showed that the rate of land use changes increased in the periods 2016-2020 and 2020-2024, while it decreased in the periods 2000-2005 and 2005-2010. These results emphasize the need for sustainable natural resource management and the development of conservation plans to control land use changes and maintain the environmental sustainability of the region.
